SEDIMENT COLLECTOR FOR. SPLASH TROUGHS.

Application filed. February 6,

To all whom it may concern:

Be it known that I, PARKER a citizen of the United States and a resident of Lynn, in the county of Essex, in the State of Massachusetts, have invented certain new and useful Improvements in Sediment Collectors for Splash Troughs, o'fwhich the following is a specification.

This invention relates to splash troughs such as are used in the crank casings of cert ain internal combustion engines, and has for its object the provision of means whereby the sediment in the oil in the trough may be collected in a member positioned in a chamher in said trough and removable'from the trough through the Wall of the crank casing.

This object is attained by the mechanism illustrated in the accompanying drawing.

For the purpose of illustrating the invention, one preferred form thereof is illus trated in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged andorganized, and the invention is not limited to the precise arrangement and organization of these inst-rumentalities as herein shown and described except as required by the scope of the appended claims.

Of the drawings Figure 1 represents a section of a crank casing having formed, integral therewith a splash trough provided with a removable sediment collector embodying theprinciples of the present invention.

Figure 2 represents a section on line 2, 2 on Fig. 1, and

Figure-3 represents a section of the crank casing and showing one sediment collector being removed from the trough by the insertion of another collector.

Similar characters indicate like parts throughout the several figures of the drawings.

In the drawings 10 isa crank casing of an internal combustion engine having formed integral therewith a trough 11 and a bottom 12 below said trough.

The oil retaining compartment 13 of the trough 11, by means of an opening 14-, com- B. IIASKELL, of America,

inunicates with a chamber to go to the barrel 20 is 1925. Serial No. 7,334.

transversely of the casing 10 opposite ends. Each end of and open at its the chamber 15 is slightly enlarged and threaded to receive a closure 16.

The oil retaining compartment is partially filled with oil and in the operation of the engine the free end of the crank 17 passes through this oil and thoroughly lubricates the bearing between the crank 17 and the connecting rod 18.

The crank 17 is with the shaft 19.-

Sediment is liable to collect in the oil and it' this gets into the bearings it is liable to do much damage and put the engineout of commission. c

It the engine is a part of a fire truck and is placed out of commission forthis or any other reason, the truck would be unable V a tire until again placed in commission.

It is therefore very desirable that every precaution should be taken to prevent injury to the engine and one means for accomplishing this is by renewing oil from time to time and keeping the oil that is in use free from sediment.

To this end asediment collector such as provided which fits accurately the cylindrical chamber this being closed at both ends and having an opening 21 in the wall thereo v p The opening 21 is adapted to register with the opening 14 so that any sediment in the oil may pass through these openings into I the interior of the barrel 20.

Between the ends of the barrel 20 and the inner ends of the closures 16 are placed packing disks 22 which are forced by said closures againstthe'ends of the barrel 20 so tightly that said'barrel is prevented from turning in the chamber 15.

A plurality of barrels 20 are kept on hand and when sufiicient sediment has collected in the barrel in use and it is desired to clean the same, both closures 16 are removed and an empty barrel is'inserted into the end of the chamber 15 against the end of the barrel in said chamber.

By applying force to the inserted barrel the filled barrel may be pushed through the 15 extending secured to and rotates chamber and removed from the opposite end thereof, the inserted barrel taking the place of that removed.

The closures 16 are then replaced and the engine is in condition immediately for further use.

The sediment in this manner may be removed from each of the troughs without interference witheither of the others, it being imderstood that the crank casing is provided with a plurality of troughs, each with its own sediment collector or barrel 20.

In another application of mine, Serial No. 732,?atl, tiled August 18, 1924, is shown a means of removing the entire trough through the wall of the casing, but many engines now in use have their crank casings provided with troughs formed integral therewith and which cannot be removed from the casing.

It is difiicult to get at such troughs for the purpose of cleaning them or freeing them from sediment.

By means of the construction herein shown and described this can be accomplished readily without obtaining access to the interior of the casing.

As a consequence much time and labor are saved as heretofore the entire casing must be dismantlec.

It is obvious that the sediment may be removed from the troughs without interfering with the operation of the engine, that is, the engine may continue in operation while the barrel is being removed and another barrel is being inserted.

It is believed that the operation and many advantages of the invention will be understood without further description.

Having thus described my invention, claim 1. A crank casing provided with a splash trough having a chamber extending lengthwise thereof from side to side'of said casing and communicating by a passage with the oil-containing compartment of said trough; a removable barrel in said chamber closed at both ends and provided with an opening normally registering with said passage; and closures for the opposite ends of said chamber.

2. A crank casing provided with a splash trough having a chamber extending lengthwise thereof from side to side of said casing and communicating by a passage with the. oil-containing compartment of said trough; a removable barrel in said chamber closed at both ends and provided with an opening normally registering with said passage; and closures threaded to the walls of said casing and adapted to close the opposite ends of said chamber.

3. A crank casing provided with a splash trough having a cylindrical chamber extending lengthwise thereof from side to side of said casing and communicating by a passage with the oil-containing compartment of said trough; a cylindrical removable barrel in said chamber closed at both ends and provided with an opening normally registering with said passage; and closures for the opposite ends oi said chamber adapted to impinge upon the opposite ends of said barrel.

4. A crank casing provided with a splash trough formed integral therewith having a chamber extending lengthwise thereof from side to side of said casing and communicating by a passage with the oil-containing compartment of said trough; a removable barrel in said chamber closed at both ends and provided with an opening normally registering with said passage; and closures for the opposite ends of said chamber.

5. A crank casing provided with a splash trough formed integral therewith and having a chamber extending lengthwise thereofthrough the opposite walls of said casing; means for closing the opposite ends of said chambe"; and a removable sediment collector in said chamber closed at both ends and provided with a peripheral opening to receive the sediment settling to the bottom of said trough.

6. A crank casing provided with a splash trough having an oil compartment with a curved bottom communicating at its lowest part with a cylindrical chamber extending from side to side of the casing; a sediment collector extending lengthwise of said chamber and adapted to be removed by the insertion of another sediment collector; and closures for the opposite ends of said chamber.

7 A crank casing provided with a splash trough having an oil compartment with a curved bottom communicating at its lowest part with a cylindrical chamber extending from side to side of the casing; a removable barrel closed at both ends extending lengthwise of said chamber and adapted to be removed by the insertion of another barrel; and closures for the opposite ends of said chamber.

8. A crank casing provided with a splash trough having an oil compartment with a curved bottom communicating at its lowest part with a cylindrical chamber extending from side to side of the casing; a barrel closed at both ends extending lengthwise of said chamber and adapted to be removed by the insertion of another barrel, said barrels being provided with peripheral inlets through which the sediment may pass to the interiors thereof; and closures for the opposite ends of said chamber.
